first.setMessage(192, 1, instrument, 0)
3
Make a MidiEvent instance for the message
MidiEvent noteOn = new MidiEvent(first, 1);
4
Add the event to the track
track.add(noteOn);
public static MidiEvent makeEvent(int comd, int chan, int one, int two, int tick) {
MidiEvent event = null;
try {
ShortMessage a = new ShortMessage();
a.setMessage(comd, chan, one, two);
event = new MidiEvent(a, tick);

}catch(Exception e) { }
return event;
}
Let’s build a static utility method that 
makes a message and returns a MidiEvent
the four arguments 
for the message
The event ‘tick’ for 
WHEN this message 
should happen
make the message and the event, using 
the method parameters
whoo! A method with five parameters.
return the event (a MidiEvent all 
loaded up with the message) 
utility method for 
events
